- inject_path_name: strip _islands/ convention dirs from path-derived names
- page-functions.sx: fix geography (→ ~geography) and isomorphism (→ ~etc/plan/isomorphic)
- request-handler.sx: rewrite sx-eval-page to call page functions explicitly
via env-get+apply, avoiding provide special form intercepting (provide) calls
- sx_server.ml: set expand-components? on AJAX aser paths so server-side
components expand for the browser (islands stay unexpanded for hydration)
- Rename 19 component references in geography/spreads, geography/provide,
geography/scopes to use path-qualified names matching inject_path_name output
